When you think of fantasy football sleepers, you normally think of young guys, maybe even rookies; guys who've shown flashes of talent but have never really gotten a chance to showcase it on a consistent basis.

The Bills have no shortage of players like that. From rookie receiver Sammy Watkins to second-year players Robert Woods and EJ Manuel to recently acquired running back Bryce Brown, Buffalo is a hot bed of "what ifs."

But we're not going to talk about any of those guys. Instead, we're going the other direction and picking a 33-year-old running back who fantasy owners have been trying to write off for the past three seasons.

Fred Jackson is still in Buffalo; he was still a top-10 fantasy RB last year (not a typo); and the Bills are still actively using formations that get both Jackson and C.J. Spiller on the field at the same time.

Yes, there will be a dropoff at some point -- productive 33-year-old RBs are rare -- but even a reduced workload for Jackson can yield RB2-caliber numbers this season. At this point, there's no reason to doubt Jackson's talent or ability to produce, both as a runner (4.3 yards per carry last year) and receiver (47 receptions).

The Bills have done a good job keeping Jackson's workload at a managable level over the course of his career, so he doesn't have the miles on his tires like, say, 30-year-old Steven Jackson or 31-year-old Frank Gore. While other fantasy owners go for "upside" with their flex-back, you can hang back and grab "boring old" Fred in the seventh or eighth round.
